The system is supposed to speed diagnostic decision making and help guide percutaneous revascularization procedures.

A comparison of how the Abbott Absorb BVS appears with intravascular ultrasound (IVUS) on the left, and optical coherence tomography (OCT) of the right. The stent is difficult to visualize and sizing is critical, so both modalities can help in bioresorbable stent measurements and to confirm stent apposition.
